Do you have a cite for your hypothesis… yes or no?
Cauldron with snakes with two handed stirring, most likely using a paddle? Most likely CCW as I’d be standing next to it. Seems that when I did concrete in a barrel, I stand with my left hip closest to the pot. Makes it easier to go with the direction I am facing.
Just realized this is similar to stirring the booyah pot. There we mostly go back and forth with a CW move every now and then interspersed with a CCw to stop the whirlpool effect.
I’m left-handed. If I stir something thick from the forearm, like chili or cement, it’s forehand (spoon sticks out of my fisted hand between thumb and forefinger like a tennis racket) and counter-clockwise. If it’s something thin and watery that doesn’t require any oomph I will sometimes hold the spoon like a pencil, and stir clockwise.
